        <div class="bz_comment_block">
          <pre class="bz_comment_text">When compiling DPDK with an earlier version than 3.7.0 of clang, CPU flags are
not detected on some Intel platforms such as Intel Broadwell/Skylake (and
possibly future CPUs), and therefore compilation fails due to missing
intrinsics.

Implication:
DPDK will not build when using a clang version < 3.7.0.

Resolution/Workaround:
Use clang 3.7.0 or higher, or gcc.

Affected Environment/Platform:
Platforms with Intel Broadwell/Skylake using an old clang version.

Driver/Module:
Environment Abstraction Layer (EAL).
